Developing safe concurrent and distributed applications with an architectural environment
Graph Chatbot
Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Well adapted to the loosely coupled nature of distributed interaction in large-scale applications, the publish/subscribe communication paradigm has recently received increasing attention. With systems based on the publish/subscribe interaction scheme, subs ...
Program verification is a promising approach to improving program quality, because it can search all possible program executions for specific errors. However, the need to formally describe correct behavior or errors is a major barrier to the widespread ado ...
Fundamentally, the development of software applications involves dealing with two distinct domains: the real world and software domains; the two converge at the point where a software application is used to make an unsatisfactory real world situation into ...
Many distributed applications have a strong requirement for efficient dissemination of large amounts of information to widely spread consumers in large networks. These include applications in e-commerce and telecommunication. Publish/subscribe is considere ...
Concurrency and failures are fundamental problems in distributed computing. One likes to think that the mechanisms needed to address these problems can be separated from the rest of the distributed application: in modern words, these mechanisms could be as ...
Despite advances in implementation technologies of distributed systems during the last few years, little progress has been made on specification techniques for describing distributed systems in software development practice. The contribution of this paper ...
We present an example of a construction of an embedded software system-a controller-from the formal specification to executable code. The CO-OPN (Concurrent Object Oriented Petri Net) formal specification language is used for modelling the controller and t ...
This paper describes a method of compiling specification properties into automata or test oracles which allow testing of any proposed implementation. It also shows how to interpret the automata's status during testing. The method addresses verification of ...
Concurrency and failures are fundamental problems in distributed computing. One likes to think that the mechanisms needed to address these problems can be separated from the rest of the distributed application: in modern words, these mechanisms could be as ...
We give a formal specification for a real-time controller for trains that operate on the Italian railway network. The controller will control train movements and is part of a larger system destined to guarantee safety with respect to dangers originating fr ...
